Dating bases mean

Talking about fifth base when there's really only four bases reminds me of the expression Up To Eleven.

If you want to downvote me for using Urban Dictionary, that's fine. First base When you get to first base, you have been lucky enough to have been kissed.

If we say home base = fourth base, that's 4 4 − 3 = 5, the subtraction because he was receiving instead of giving.

But this is a joke, and probably not intended to be analyzed too closely. Although this wasn't what "House" referred to, Urban Dictionary lists fifth base as anal sex.

If one person puts their hands or mouth on the other person’s genitals, they’re on third base.

Third base may include manual or oral sex for either partner.Some people only consider French kissing as getting to first base.Second base is direct physical contact, usually meaning his hands to her breast.One of the other answers has provided a nice link to the Wikipedia entry for baseball metaphors for sex.There are, as the top comment on this question notes, four bases in baseball, and these have corresponding sex acts associated with them.This generally means that the couple had penis-vagina sexual intercourse if the partners are male and female. If the partners are two women, then this model of “scoring” by “sliding into home” kind of doesn’t work. This means that the batter who can’t hit the ball is essentially the loser. In real life, however, a strikeout is not a failure. If they ask what you’re doing, in your best prospector voice just reply with, “I be lookin’ for gold in deez der hills.” (Note: that is not going to help the situation…only worsen it.) This is where some people’s base running analogies change it up. Playing “Just the Tip”….ehh, that’s like a 3rd base lead-off. I should write for like a men’s health magazine or some shit. Sure it raises the blood pressure, and probably brings them on the verge of keeling over mid coitus, but that’s all part of the thrill!A home run is full on penetration…well, then followed by repetitive motions perhaps at multiple angles to achieve differing sensations…WHICH, lead to the body reaching a climactic point. All in all, that’s my understanding of base running and a sexual relationship.
